Textbook Question
Chapter 12.2, Problem 6CE
Forestry A forest ranger wishes to determine the velocity of a stream. She throws an object into the stream and clocks the time it takes to travel a premeasured distance of 200 ft. She then divides the time into 200 to calculate the velocity in feet per second. For greater accuracy, she repeats this process four times and finds the mean of the four velocities. If the four trials result in times of 21, 23, 20, and 23 sec, calculate the mean velocity to the nearest 0.1 ft/sec.

1 (Expected Shortfall)
Suppose the price of an asset Pt follows a normal random walk, i.e., Pt =
Po+r₁ + ... + rt with r₁, r2,... being IID N(μ, o²).
Po+r1+.
⚫ Suppose the VaR of rt is VaRq(rt) at level q, find the VaR of the price
in T days, i.e., VaRq(Pt – Pt–T).
